This provides a mixture of the dates of significant events (such as “the first X”) and various counts of usage at the anniversaries of the launch (each 27 September).

Counts of products and companies that use DNG in some way are provided primarily for illustration. They are approximate, and include products that are no longer sold. The purpose is mainly to demonstrate that such products and companies exist, and to show trends. Convertible raw image formats (camera models whose raw images can be converted to DNG) only include official support by Adobe DNG converters; not unofficial support by Adobe products (sometimes reaching about 30), nor support by other DNG converters; (Adobe is not the only company supplying a DNG converter).

(The table merges a similar table that I created in Wikipedia with A brief history of DNG. There are some small variations, for example because of uncertainty of launch dates, etc).

Overview of DNG use in cameras

During the first 5 years when about 38 camera models were launched that wrote DNG, Adobe software added support for about 21 Canon models, about 20 Nikon models, and about 22 Olympus models. Camera models that write DNG are almost certainly launched at a higher rate than camera models that support any other individual raw image format, including NEF, CR2, and ORF.

DNG is the raw file format of choice for niche, and some minority, camera and digital back manufacturers. It supports a greater variety of types of camera than any other raw file format.
